WEATH ER-STRI P.

SPECIFICATION formingpart of Letters Patent No. 408,949, dated August 13, 1889.

Application filed November 10, 1888- $erial No. 290,450. (No model.)

To all whom it may concern.-

Be it known that I, JOHN BURNHAM, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in WVeather-Strips, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a new and useful improvement in weather-strips for doors; and the invention consists in the peculiar construction, arrangement, and combination of the different parts, all as more fully hereinafter described, and set forth in the accompanying drawings, in which- Figure 1 is an elevation of a door and doorsill to which my device is secured. Figs. 2 and 3 are vertical cross-sections through the door and door-sill, the former showing the door open and the latter showing it closed.

A is the door, and B is the door-sill.

O is a molding secured near the lower end of the door, and provided with a recess D upon its lower edge.

E is a tilting slat secured along the lower edge of the molding by means of suitable hinges F, and projecting with its upper end within the recess of the molding, and with its lower edge in proximity to the plane of the door-sill. This tilting slat is free to tilt from the inclined position shown in Fig. 2 into the vertical position shown in Fig. 3, the inclined position shown in Fig. 2 being the normal position of the slat, which it assumes by making that portion of the slat above the hinges wider or heavier than that portion of the slat below the hinges, and bymaking the slat preferably of sheet or cast metal. G is another tilting slat hinged at its lower edge to the inclined outer face of the door-sill, which latter is provided with a corresponding recess H, within which the tilting slat G is adapted to fold and form a complementary part of the door-sill. This folding slat extends the whole length of the door-sill and the whole width, or nearly so, of the outer inclined face thereof, and is provided with an arm I, which extends upwardly into the path of the lower edge of the tilting slat E.

The threshold B, I preferably make of cast iron or sheet metal, and instead of hinging the slat G to the said door-sill it may have laterally-proj ecting pivots extending into the door-casings, as shown in Fig. 1.

In practice, the parts being arranged and constructed as described, the operation of the device is as follows: When the door is open, the tilting slat E, carried by the door; is held by the action of its gravity (or by the action of a spring concealed within the recess) in the inclined position shown in Fig. 2, which withdraws its lower edge sufficiently from the top of the door-sill or the carpet on the floor to permitthe door being freely opened and closed. Then the door is closed, the lower edge of the tilting slat E strikes the arm I of the tilting slat G, and therebysimultaneously lifts up said slat out of its recess and tilts itself upon its hinges, so that when the door is fully closed a lap-joint is formed between the two slats, as shown in Fig. 3.

What I claim as my invention is 1. In a weather-strip for doors, the combination, with the door and door-sill, of two tilting slats, one carried by the door and normally inclined from its vertical position, and the other being located on the outer inclined face of the door-sill and provided with an arm projecting into the path of the tilting slat carried by the door, the tilting slats cooperating to form a lap-joint, substantially as and for the purpose described.

2. I11 a weather-strip for doors, the combination, with the door and door-sill, of the molding 0, provided with the recess D, the tilting slat E, hinged to the lower edge of said molding and being normally inclined by the action of its gravity, the tilting slat G, hinged or pivotally secured at its lower edge and proj ecting upwardly upon the outer inclined face of the door-sill, and the arm I, projecting into the path of the tilting slat E, the parts being arranged to operate substantially as and for the purpose described.

3. In a weather-strip for doors, the combination, with the door, of the molding O, provided with the recess D, the tilting slat E, hinged to the lower edge of said molding and projecting partly within said recess and partly below the molding and normally inclined by the action of its gravity, the doonsill 13, pro Vided with the recess H, the tilting slat G, adapted to fold within said recess, and the arm I on that tilting slat projecting within 5 the path of the tilting slat E, substantially as and for the purpose described.

4. In a weather-strip, the eo1nbination,with the door and door-sill, of two tilting slats, one carried by the door, and the other being [0 located upon the sill of the door and provided with an arm projecting into the path of the tilting slat carried by the door said tilting slats being normally inclined from the Vertical position and adapted to be inclined in a substantially vertical position and form a lapjoint, substantially as and for the purpose described.

In testimony whereof I mix my signature, in presence of two witnesses, this 25th day of June, 1888.

JOHN BURNIIAM.
